READ: How neglecting bees could endanger humans

Bees pollinate much of our food supply, but a pesticide threatens their survival

If you are an almond farmer in the Central Valley of California, where 80 percent of the world’s production is grown, you had a problem earlier this spring. Chances are there weren’t enough bees to pollinate your trees. That’s because untold thousands of colonies — almost half of the 1.6 million commercial hives that almond growers depend on — failed to survive the winter, making this the worst season for beekeepers in anyone’s memory. And that is saying a lot, because bees have been faring increasingly poorly for years now.

Much of this recent spike in bee mortality is attributed to Colony Collapse Disorder, a mysterious condition where all the worker bees in a colony simply fly off as a group and never make it back to the hive. Scientists have been studying this odd phenomenon for years and they still aren’t sure why it is happening.

But a slew of recent studies have pointed an accusing finger at a class of pesticides, the ubiquitous neonicotonoids (neonics for short), which include imidacloprid and clothianidin, manufactured by Germany’s agro-giant Bayer, and thiamethoxam, made by Syngenta. The neonics, the world’s leading insecticides, are applied on a whopping 75 percent of the farmlands in America, according to Charles Benbrook, research professor at Washington State University’s Center for Sustaining Agriculture and Natural Resources. Neonics are a so-called systemic pesticide. That means that they are taken up by the plant’s vascular system and get impregnated into all parts of the plant that an insect encounters, including the leaves, seeds, nectar and pollen. Corn and soybean seeds are typically coated with the pesticide before planting. Fruit trees and many vegetables are sprayed.

Few researchers believe that the neonics alone are to blame for the bees’ troubles, which appear to result from a perfect storm of contributing environmental factors. Pollinators have been called the canaries in the coal mine for ecosystem health. The declining numbers of both wild species and domesticated bee colonies worldwide is regarded as a troubling barometer of the state of the environment, reflecting habitat loss, the spread of agricultural monocultures, infestation by viral pathogens and bee parasites like the Varroa mite, climate change and even electromagnetic radiation, which seems to interfere with bees’ homing ability.

But the neonics, which contains a chemical related to nicotine that attacks an insect’s nervous system, have been demonstrated to kill bees — and especially the queens — when applied in high enough doses. And a growing body of research suggests that at sub-lethal concentrations, these agro-chemicals mess with their navigation, foraging and communication abilities, throw off their reproductive patterns, and weaken bee immune systems, making them susceptible to sudden colony collapse.

One study published by scientists at Purdue University in 2012 showed high levels of clothianidin and thiamethoxam in bees found dead near agricultural fields. Other bees at the hives were observed exhibiting uncoordinated movement, tremors and convulsions, all signs of insecticide poisoning.

In yet another study conducted by scientists at the Harvard School of Public Health, which I reported on in Reuters last April, researchers actually re-created colony collapse disorder in several honeybee hives simply by administering small doses of a popular neonic, imidacloprid.

These and other recent studies led the European Union to call on Monday for a provisional ban on neonics for two years to see what impact this has on Europe’s endangered bees. The use of the pesticides had already been temporarily suspended in Germany, France and Italy.

The vote in Brussels was split (15 of the 27 EU countries voted for the ban). The British Newspaper the Observer said that there was “a fierce behind the scenes” campaign to prevent the ban. The paper reported that agricultural multinational Syngenta, facing what it called “serious damage to the integrity of our product and reputation,” threatened to sue individual European Union officials involved in publishing the damning report about the dangers of neonics. The U.K. voted against the ban, alleging that the science is inconclusive and that barring the pesticides would be hugely expensive and potentially cripple food production.

But the ban had lots of public support, including a petition signed by over 2.5 million Europeans. And it was universally applauded by environmentalists, who have been fighting for it for years. Andrew Pendleton of the U.K division of Friends of the Earth said: “This decision is a significant victory for common sense and our beleaguered bee populations. Restricting the use of these pesticides could be an historic milestone on the road to recovery for these crucial pollinators.”

Pressure has been building in the U.S. to restrict the neonics. A coalition of beekeepers and environmental groups filed suit in March against the U.S. Environmental Protection Agency for its failure to ban the pesticides, saying that the agency didn’t consider the impact of the pesticides on vital pollinators. The American Bird Conservancy published in March a review of 200 studies on neonics, including industry research obtained through the U.S. Freedom of Information Act, which concluded that the neonics are lethal to birds and other wildlife and to the aquatic systems on which they depend.

These threats to wildlife are significant, but the world’s attention is rightly focused on bees, which are responsible for pollinating nearly a third of our food supply. These industrious insects are in serious trouble. And if their decline continues unchecked, we humans may soon be in trouble too.

Mystery Malady Kills More Bees, Heightening Worry on Farms
By 

BAKERSFIELD, Calif. — A mysterious malady that has been killing honeybees en masse for several years appears to have expanded drastically in the last year, commercial beekeepers say, wiping out 40 percent or even 50 percent of the hives needed to pollinate many of the nation’s fruits and vegetables.

A conclusive explanation so far has escaped scientists studying the ailment, colony collapse disorder, since it first surfaced around 2005. But beekeepers and some researchers say there is growing evidence that a powerful new class of pesticides known as neonicotinoids, incorporated into the plants themselves, could be an important factor.

The pesticide industry disputes that. But its representatives also say they are open to further studies to clarify what, if anything, is happening.

“They looked so healthy last spring,” said Bill Dahle, 50, who owns Big Sky Honey in Fairview, Mont. “We were so proud of them. Then, about the first of September, they started to fall on their face, to die like crazy. We’ve been doing this 30 years, and we’ve never experienced this kind of loss before.”

In a show of concern, the Environmental Protection Agency recently sent its acting assistant administrator for chemical safety and two top chemical experts here, to the San Joaquin Valley of California, for discussions.

In the valley, where 1.6 million hives of bees just finished pollinating an endless expanse of almond groves, commercial beekeepers who only recently were losing a third of their bees to the disorder say the past year has brought far greater losses.

The federal Agriculture Department is to issue its own assessment in May. But in an interview, the research leader at its Beltsville, Md., bee research laboratory, Jeff Pettis, said he was confident that the death rate would be “much higher than it’s ever been.”

Following a now-familiar pattern, bee deaths rose swiftly last autumn and dwindled as operators moved colonies to faraway farms for the pollination season. Beekeepers say the latest string of deaths has dealt them a heavy blow.

Bret Adee, who is an owner, with his father and brother, of Adee Honey Farms of South Dakota, the nation’s largest beekeeper, described mounting losses.

“We lost 42 percent over the winter. But by the time we came around to pollinate almonds, it was a 55 percent loss,” he said in an interview here this week.

“They looked beautiful in October,” Mr. Adee said, “and in December, they started falling apart, when it got cold.”

Mr. Dahle said he had planned to bring 13,000 beehives from Montana — 31 tractor-trailers full — to work the California almond groves. But by the start of pollination last month, only 3,000 healthy hives remained.

Annual bee losses of 5 percent to 10 percent once were the norm for beekeepers. But after colony collapse disorder surfaced around 2005, the losses approached one-third of all bees, despite beekeepers’ best efforts to ensure their health.

Nor is the impact limited to beekeepers. The Agriculture Department says a quarter of the American diet, from apples to cherries to watermelons to onions, depends on pollination by honeybees. Fewer bees means smaller harvests and higher food prices.

Almonds are a bellwether. Eighty percent of the nation’s almonds grow here, and 80 percent of those are exported, a multibillion-dollar crop crucial to California agriculture. Pollinating up to 800,000 acres, with at least two hives per acre, takes as many as two-thirds of all commercial hives.

This past winter’s die-off sent growers scrambling for enough hives to guarantee a harvest. Chris Moore, a beekeeper in Kountze, Tex., said he had planned to skip the groves after sickness killed 40 percent of his bees and left survivors weakened.

“But California was short, and I got a call in the middle of February that they were desperate for just about anything,” he said. So he sent two truckloads of hives that he normally would not have put to work.

Bee shortages pushed the cost to farmers of renting bees to $200 per hive at times, 20 percent above normal. That, too, may translate into higher prices for food.

Precisely why last year’s deaths were so great is unclear. Some blame drought in the Midwest, though Mr. Dahle lost nearly 80 percent of his bees despite excellent summer conditions. Others cite bee mites that have become increasingly resistant to pesticides. Still others blame viruses.

But many beekeepers suspect the biggest culprit is the growing soup of pesticides, fungicides and herbicides that are used to control pests.

While each substance has been certified, there has been less study of their combined effects. Nor, many critics say, have scientists sufficiently studied the impact of neonicotinoids, the nicotine-derived pesticide that European regulators implicate in bee deaths.

The explosive growth of neonicotinoids since 2005 has roughly tracked rising bee deaths.

Neonics, as farmers call them, are applied in smaller doses than older pesticides. They are systemic pesticides, often embedded in seeds so that the plant itself carries the chemical that kills insects that feed on it.

Older pesticides could kill bees and other beneficial insects. But while they quickly degraded — often in a matter of days — neonicotinoids persist for weeks and even months. Beekeepers worry that bees carry a summer’s worth of contaminated pollen to hives, where ensuing generations dine on a steady dose of pesticide that, eaten once or twice, might not be dangerous.

“Soybean fields or canola fields or sunflower fields, they all have this systemic insecticide,” Mr. Adee said. “If you have one shot of whiskey on Thanksgiving and one on the Fourth of July, it’s not going to make any difference. But if you have whiskey every night, 365 days a year, your liver’s gone. It’s the same thing.”

Research to date on neonicotinoids “supports the notion that the products are safe and are not contributing in any measurable way to pollinator health concerns,” the president of CropLife America, Jay Vroom, said Wednesday. The group represents more than 90 pesticide producers.

He said the group nevertheless supported further research. “We stand with science and will let science take the regulation of our products in whatever direction science will guide it,” Mr. Vroom said.

A coalition of beekeepers and environmental and consumer groups sued the E.P.A. last week, saying it exceeded its authority by conditionally approving some neonicotinoids. The agency has begun an accelerated review of their impact on bees and other wildlife.

The European Union has proposed to ban their use on crops frequented by bees. Some researchers have concluded that neonicotinoids caused extensive die-offs in Germany and France.

Neonicotinoids are hardly the beekeepers’ only concern. Herbicide use has grown as farmers have adopted crop varieties, from corn to sunflowers, that are genetically modified to survive spraying with weedkillers. Experts say some fungicides have been laced with regulators that keep insects from maturing, a problem some beekeepers have reported.

Eric Mussen, an apiculturist at the University of California, Davis, said analysts had documented about 150 chemical residues in pollen and wax gathered from beehives.

“Where do you start?” Dr. Mussen said. “When you have all these chemicals at a sublethal level, how do they react with each other? What are the consequences?”

Experts say nobody knows. But Mr. Adee, who said he had long scorned environmentalists’ hand-wringing about such issues, said he was starting to wonder whether they had a point.

Of the “environmentalist” label, Mr. Adee said: “I would have been insulted if you had called me that a few years ago. But what you would have called extreme — a light comes on, and you think, ‘These guys really have something. Maybe they were just ahead of the bell curve.’”

“Bay Area’s ‘urban’ bees like native, diverse plantings”

By Lou Fancher via mercurynews.com

Bay Area's 'urban' bees

Dr. Gordon Frankie said native bees have preferences, and knowing what they like can improve the health of your garden.

“If they have a choice, they’ll go after native plants,” said Frankie, a professor and research entomologist at UC Berkeley. He and Steve Gentry, a founding member of the Mount Diablo Beekeepers Association, teamed up for a recent Lafayette Library Foundation Science Cafe presentation.

Frankie’s point — that local gardeners hoping to attract Agapostemon texanus or Xylocopa varipuncta, two local native bee species, should include native plants in their gardening plans. And mulching should be done lightly because 70 percent of all native bees nest in the ground and can’t burrow through materials heavier than soil.

A project at Frog Hollow Farm and other Brentwood farms is demonstrating the impact of placing native plants between crop rows.

Urban areas are ideal for bees, Frankie claimed, because of the diverse food supply they offer. The Oxford Tract Bee Garden he and his team of researchers planted allows them to monitor and categorize bees’ attraction to native and nonnative plants. A 10-city survey across California is providing a detailed picture of the bee population. San Diego, he said, is the worst city for attracting bees.

“It’s their gardening culture: No one is using diverse, floral plants,” Frankie said.

On the other end of the spectrum, a 30-by-30-foot garden in Ukiah had 68 bee species, and Santa Cruz is a hotbed beehive community. (The Bay Area is fifth on that list.)

Gentry, known by local residents as “Bee Man” — although he is considering an upgrade to “Emperor of Bees” — began the popular event’s 60-minute talk with a bucket.

“All of these products from bees are helpful to humans,” he declared, pulling hunks of beeswax and jars of honey, pollen and actual bees from the container. “Their history goes back thousands of years.”

Within five minutes, Gentry had advocated (beeswax is used for lubricants in cosmetics, candles, wax-resist dyeing and food preserving), acknowledged (“We have some hindrance about eating insects, but watch a bear break into a bee’s nest. He’ll eat the whole thing,” he said), and advertised (pollen is the new superfood, with protein, enzymes, vitamins and minerals, according to Gentry).

He also shared a 30-year-old epiphany he had while watching a black bear and her two cubs demolish a rotted tree while feasting on termites.

“I wasn’t the first person to see natural things. Forty thousand years ago, hunter-gatherers watched bears, bees and insects, too. The timeline is long,” he said.

Skipping through honeybee history, from Middle Eastern origins to monks in monasteries needing dependable light sources to small farmers before World War I who kept just enough hives to feed their families and pollinate their crops, Gentry landed on the contemporary world’s bee dilemmas.

“Industrialization changed farms. They became bigger, and now, large pollination contracts and commercial beekeeping are driving the business. (More than a million) hives are brought into the central Southern California valley for pollinating almonds each year.”

Frankie, whose business is less about keeping bees and more about watching them, asked the Science Cafe audience of gardeners, beekeepers and general science fans a series of questions.

Delighting at stumping his listeners, he said 1,600 bee species were attracted to California’s 5,000 flowering plants, drawing a hefty percentage of the United States’ 4,000 total bee species.

“Notice, you are not on their list,” he said. “Bees are vegetarians. They’re not after you or your burgers. Wasps are the ‘meat bees’ after your burgers.”

Generating a local buzz
The University of California Press will publish Gordon Frankie’s findings in a forthcoming book, “Native Bees and Their Flowers in Urban California Gardens.” Bee appreciators who don’t want to wait can find information at http://nature.berkeley.edu/urbanbeegardens/index.html and diablobees.org.
